Question

The dimensions of a rectangular park are 25 cm by 15 cm . Rohit takes 5 rounds of the park. How much distance does he cover​

Answer 1

Answer:

1575 square cm

Step-by-step explanation:

length=25

bredth=15cm

area=l into b

=375cm square

5 rounds=375 into 5=1575 cm square

Answer 2

Answer:

✳ Distance covered by Rohit in 5 rounds around the park = 400 cm.

✳SOLUTION✳

Length (l) of the rectangular park = 25 cm.

Breadth (b) of the rectangle = 15 cm.

The Rectangular Park Is:-

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(5,0){2}{\line(0,1){3}}\multiput(0,0)(0,3){2}{\line(1,0){5}}\put(0.03,0.02){\framebox(0.25,0.25)}\put(0.03,2.75){\framebox(0.25,0.25)}\put(4.74,2.75){\framebox(0.25,0.25)}\put(4.74,0.02){\framebox(0.25,0.25)}\multiput(2.1,-0.7)(0,4.2){2}{\sf\large 25 cm}\multiput(-1.4,1.4)(6.8,0){2}{\sf\large 15 cm}\put(-0.5,-0.4){\bf A}\put(-0.5,3.2){\bf D}\put(5.3,-0.4){\bf B}\put(5.3,3.2){\bf C}\end{picture}$

$\red\bigstar$ Distance covered by Rohit in one round around the rectangular park = Perimeter of the rectangular park

$\red\bigstar \boxed{ \sf Perimeter \: of \: the \: Rectangular \: park = 2(l+b)}$

Perimeter of the rectangular park = 2( 25 + 15 )

Perimeter of the rectangle park = 2 × 40

Perimeter of the rectangle park = 80cm.

Distance traveled by Rohit in one round around the rectangular park = 80cm.

✩ Distance traveled by Rohit if he takes 5 rounds = 5 × 80 = 400cm.
